An authenticated user who gains access to this sensitive information could leverage it to perform unauthorized read operations on SNMP tables or to send fraudulent trap notifications to the Network Management System (NMS). This issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks.
